EXHAUST-NOZZLE.

SPECIFICATION forming part of Letters Patent No. 300,819, dated June 10,188s.

Application filed February 8, 1884. (No model.)

To all whom it may concern: the nozzle on the line ab, and -Fig. 4 asimilar Be it known that I, GEORGE D. HUNTER, a view showing more thanone passage through citizen of the United States, residing at Terre thedischargeneck. Haute, in the county of Vigo and State of In- The letterA indicates the body of my inidiana, have invented certain new anduseful proved exhaustnozzle, the same being con- Improvements inExhaust-Nozzles, of which structed, preferably, of cast-iron and oftaperthefollowingisaspecification, reference being ing form, asindicated in the drawings. At 5 had therein to the accompanyingdrawings. its upper end it is providedwith a thimble, B, This inventionrelates to certain new and usewhich serves to contract the mouth thereofto m ful improvements in steam-exhaust nozzles, any requisite degree.Near its base, and at and it has special reference to that class useddiametrical points, preferably, its walls are in locomotives. contractedand curved inwardly, as reprc- 6o The invention has for its objects,first, to sentcd by the letter O, the object of which is provide anexhaust-nozzle having a partition to prevent the exhaust-steam fromaccuniulat in the lower part thereof, with a lateral dising or beingobstructed, and to make it discharge-neck having more than one passagecharge centrallythrough the nozzle. Should throughit; second, to provideanexhaustnon the curvature of the wall of the nozzle be in zle havingits walls contracted at dianietrical the opposite direction, as shown indotted points, and a partition located in the lower lines, the tendencywould be to direct or de- 20 part thereof, with a lateraldischarge-neck; fleet the steam from one side of the nozzle tothird, toprovide an exhaust-nozzle having its ward the other, instead of allowingit to eswalls contracted at diametrical points, and a cape in a directway. The nozzle is also propartition located in the lower part thereof,vided near its base with a vertical partition, with a lateraldischargeneclc having one or D, which extends up to about onc-third themore passages through it; and, f0urth,to proheight of the nozzle, andthere terminates, vide an. exhaust-nozzle having its walls conwherebythe discharge of the steam is caused tracted at diametrical points, witha lateral. to issue in a single volume. This partition 7 discharge-neckhaving one or more passages also aids in directing the steam upwardly,as through it. above described. Extendingfromtheforward -c \Vith theseends in view my invention conside of the nozzle, embracing the planeoccu- 0 SiStS, essentially, of a tubular tapering n'ozzle pied by thepartition I), is alatcral discharge having its walls contracted atdianietrical neck, E, an aperture being formed in the wall points, and apartition in its lower portion, of the nozzle at this point, wherebydirect comand provided with a lateral discharge-neck. inunication isestablished between the interior 35 In the accompanying drawings,forming a of the nozzle at either side of the partition part of thisspecification, and on which like with the smoke-box. The wall of thenozzle,

letters of reference indicate corresponding a. short distance at eachside of this neck, is dentures, Figure 1 represents a verticalsecslightly flattened, so as to form a tapering tional view of myimproved exhaust-nozzle as lead to the passage through the neck, whereby4o constructed with alateral discharge-neck hava more ready lateraldischarge of the steam is ing one passage through it, the section beinginduced. This neck maybe dividedlongituditaken on a line coincident withthe longitudt nally about the center by a distended portion, nal axis ofthe locomotive-boiler when the noz- F, of the partition I), or by aseparate partizle is placed in position; Fig. 2, a vertical section,each passage being provided with thinr tional view of the nozzle, takenon a line at blcs G, whereby the area of the mouth may right angles tothe line of the above section, be contracted, as required. Itwill beobserved looking in the direction of the arrow, as seen that by reasonof this lateral discharge of the 5 in 1 Fig. 3, ahorizontal sectionalview of steam the sparks, cinders, or other more solid particles ofcombustion collecting in the lower part of the smoke-box are forced intoa conduit so located as to receive and conduct them to a suitablereceptacle, such as shown and de- I scribed in my Letters Patentnumbered 285,899 and 285,900, and dated October 2, 1883.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is

1. An exhaust-nozzle having a partition in the lower part thereof, andprovided with a lateral dischargencck having more than one passagethrough it.

2. An exhaust-nozzle having alateral discharge-neck and a partition inthe lower part thereof distended through said neck.

3. An exhaust-nozzle having its walls contracted at diametrical pointsand a partition located in the lower part thereof, and provided withalateral discharge-neck.

4. An exhaust nozzle having its walls contracted at diametrical pointsand a partition located in thelower part thereof, and provided with alateral discharge-neck having one or more passages through it. I

5. An exhaustnozzle having its walls contracted, and a lateraldischarge-neck, and provided with a partition in the lower part thereofdistended through said neck.

6. An exhaust-nozzle having its walls contracted at diametrical points,and provided with a lateral discharge-neck having one or more passagesthrough it.

7. An exhaust-nozzle having its walls contracted at diametrical points,and provided with a dischargeneck.

In testimony whereof I affix my signature in presence of two witnesses.

GEO. -D. HUNTER.
